The raw water is passed through a pressure sand filter at a pressure of 3.5 kg/cm². This pressure is applied to force the water through the filter medium, which removes suspended solids.
Pressure Sand Filter Details
Here's a breakdown of the pressure and its purpose within a pressure sand filter system:
- Pressure: 3.5 kg/cm²
- Purpose: To drive the raw water through the filter bed, facilitating the removal of suspended solids.
- Filtration Capability: This pressure allows the filter to effectively remove suspended solids down to 30-50 microns in size, reducing the concentration to less than 5 ppm (parts per million).
In summary, the pressure in a pressure sand filter (like the one described) is specifically set at 3.5 kg/cm² to efficiently remove suspended solids from the raw water supply.
